Want the ring?

How effective is NuvaRing?

When used perfectly, the NuvaRing is 99% effective. But when it comes to real life, the ring is about 91% effective because it can be hard to be perfect. So in reality, 9 out of 100 ring users get pregnant each year.

The better you are about putting in a new NuvaRing on the right day every month, the better it will work. But there’s a very small chance that you could still get pregnant, even if you always use the ring correctly.

If effectiveness is the most important thing to you when picking what birth control to use, you might want to check out IUDs and the implant. They’re the most effective kinds of birth control. But if you decide the ring is right for you, make sure you change it on time every month for the best effectiveness.

What makes NuvaRing less effective?

If you don’t use the ring correctly, it can’t work well. That means you’re more likely to get pregnant if you don’t put a new ring in on time every month, or if the ring’s out of your vagina for more than 2 days (48 hours) during the weeks when you’re supposed to be wearing it.
